Initial support for finding the ACE and TAO installations using $ACE_ROOT and $TAO_ROOT respectively.  This change also fixes some typos in the TAO detection code that did not show up when I had ACE+TAO installed in /usr/local.

NOTE: The dependency distribution build has not been updated to allow the
      use of $ACE_ROOT and $TAO_ROOT.  That is going to be a little more
      complicated, but I am working on a revamped process for bundling
      depenencies that should fix this and other problems.
